Bug#910377: Inhibit reboot/shutdown if dpkg is running

[Laurent Bigonville]

Package: systemd
Version: 239-10
Severity: wishlist

Hi,

Not sure if this should be reported here or in dpkg

Shouldn't it be intresting to add a hook in dpkg to inhibit the
reboot/shutdown of the machine while packages are being
updated/installed?

Kind regards,

Laurent Bigonville
